Helllo,
I am trying to use BSEC v1.8.1492 driving a BME680 sensor using ESP32 chip, I am using Arduino framework and PlatfotmIO.
Previously I used BSEC Software Library v1.6.1480 and everything worked smoothly but I couldn't make it work after updating the BSEC to the latest version (1.8.xxxx).
I basically used the official example in github
https://github.com/boschsensortec/BSEC-Arduino-library/blob/master/examples/basic_config_state/basic...
So basically iaqSensor.run() is always false but it seems to work once I commented iaqSensor.setConfig(bsec_config_iaq);
and here is the actual code I am using
#include <bsec.h>
#include <Wire.h>
#include <Arduino.h>
const uint8_t bsec_config_iaq[] = {
#include "config/generic_33v_3s_4d/bsec_iaq.txt"
};
#define SERIAL_BAUDRATE 115200
#define EEPROM_SIZE 512
#define VERBOSE true
#define DEVICE_NAME "Connected Ambiente"
//* I2C Pins
#define I2C_SDA_PIN GPIO_NUM_13
#define I2C_SCL_PIN GPIO_NUM_15
#define OLED_Address 0x3c
#define I2C_Frequency 400000
